Adamant Custom 24-Core Workstation

This business desktop pairs a 24-core Intel Core i9-14900K with 128GB of DDR5 memory and an Nvidia RTX PRO 5000 Blackwell GPU. It includes a 1TB NVMe SSD and a 10TB hard drive for project storage. Liquid cooling and a 1200W power supply support sustained workloads in a tower chassis.

Who This Suits and Who It Does Not

Engineers running SolidWorks, CAD or CAE simulations will benefit from the 48GB GPU memory and high core count. Buyers who need more than 192GB of system memory or a dual-GPU configuration should consider a different platform. This system targets professional modelling rather than general office use.

48GB GPU Memory Decides Fit

The RTX PRO 5000 Blackwell provides 48GB of video memory, which determines whether large assemblies and datasets fit in GPU memory. If your workflow exceeds this capacity, the card becomes the bottleneck regardless of the 128GB system RAM or 24 CPU cores.

Questions about this item

Can I keep using my current SATA 6Gb/s hard drives with the Z790 PRIME motherboard in this tower?

Yes, the board provides four SATA 6Gb/s ports so existing SATA drives connect directly.

How can I verify the Samsung 990 PRO 1TB NVMe is running at PCIe 4.0 x4 speeds after I set up Windows 11 Pro?

Open Task Manager, go to the Performance tab, select the SSD and confirm the link reads PCIe 4.0 x4 with read speeds near 7450 MB/sec.

What cooling and power items are already installed, and what must I supply myself?

The system ships with a 360 mm liquid CPU cooler and a 1200 W 80 PLUS Gold PSU installed; you only need to add a monitor, keyboard and mouse.
